Translations - plural singular / more complex way

Does any of you has an idea about a solution for translating singular / plural in a more complex way ? I say more complex, because in certain languages (like Romanian) the plural or the singular can completely modify the syntax. For example:

English: 1 minute ago
Romanian: Acum 1 minut (or In urma cu 1 minut)

English: 2 minutes ago
Romanian: Acum 2 minute

English: 21 minutes ago
Romanian: Acum 21 de minute

This is a dummy example, but the things can go more complex than this. So, if any of you has an idea about how i can manage this without adding tons of different translations ... you are the man ! :)
